transformation

In April 2001, 2 DPMS? 600 mm x 1000 mm, single cylinder dry-Intensity Permanent Magnetic Separator were adopted, they completed in advance to come up from the crushing operation closed cycle lean ore particle size of mm – 30 mm + 16 mm, iron grade is 54. 00% 55.00%, the qualified testing and production of lump ore transformation. You may 2001 production date, each year from the crushing operations to come up with the iron grade in advance 54.OO% to 55.00%. 5 60 000 t of production qualified to pray, not only a benefit for more than 4 million yuan, but also reduced the secondary crushing capacity and ore had crushed.Do DPMS-? 300 mm 1OOO monocular Noms dry-Intensity Permanent Magnetic Separator broken to screening-T intensity magnetic separation process to complete the – 40 mm + 10 mm concentrator crushing operation near the plant, in April 2002 The industry qualified test and production upgrading of the bonanza mine. The production results show that the iron concentrate grade is 53.00% to 56 00%, industry than production of iron grade 51 00% 53 or improved by 2-3 percentage points. Not only solving the screen wash the fine mud discharge (into the processing plant Dam), but also improving the iron grade of jaw crusher, and yield increase economic returns 4.96 million yuan. It may-June 2002 production of iron grade is 54.50% above. Do In recent years, Maanshan Iron & Steel Group Kou Shan Mining Company concentrator adopts the 15 th 6 mm DPMS-? 300 mm x 1000mm ten style Intensity Permanent Magnetic Separator machine production targets.

Dounan manganese. 30. 15 mm, and 15 th to 6 mm manganese ore and third generation the DPMS plow dry Intensity Permanent magnetic separator machine selection index contrast. Magnetic field strength of the second generation of DPMS dry-Intensity Permanent Magnetic Separator, Due to the increased magnetic field depth, the valley changed the magnetic field distribution in the separation of 30-15 mm and 15 th 6 mm manganese, with the first generation of DPMS type, The dry type Intensity Permanent Magnetic Separator separation indexes compared in the ore grade and concentrate grade is equivalent to the case of fine mineral, which increased by 6 63-11 94%, tailing grade reduced by 336-449 percent, and the recovery rate improved about 10.90 to 19.42 percents, indicating that the third generation of DPMS dry-Intensity Permanent Magnetic Separator points selected + 6 mm of weakly magnetic minerals, the separation indexes received a substantial increase.
